Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490160, here are decompositions:

43 + 490117 = 490160
103 + 490057 = 490160
127 + 490033 = 490160
157 + 490003 = 490160
199 + 489961 = 490160
313 + 489847 = 490160
337 + 489823 = 490160
367 + 489793 = 490160

Showing the first eight; more decompositions exist.
